India’s proposed apparel size framework could curb online returns and simplify fit decisions
The Indian Size System is being finalised as a common, India-specific apparel sizing baseline. Brands including Blackberrys and Madame support the move but want flexibility for fit and design, with adoption likely to be gradual across collections.
What happened
Indian Size System (ISS) · India’s proposed standard apparel-sizing framework could improve consumer confidence, simplify online purchases and reduce
Key facts
- Indian apparel market projected at ₹16 lakh crore by FY30
- Indian apparel market estimated at ₹9.30 lakh crore in FY25
- Organised segment represents nearly 41% of the industry
Why this matters
The framework creates opportunities for fit-tech, virtual try-on, sizing-data and returns-management partners that can help brands implement a common baseline without sacrificing differentiated fit.
What to watch
- Publication of final Indian Size System specifications, governance rules and adoption timetable.
- Whether adoption is voluntary, tied to Bureau of Indian Standards guidance, or incorporated into labelling or marketplace compliance requirements.
- Commitments from major marketplaces and large national brands to make standard-size fields mandatory in listings.
- Evidence from pilot brands of changes in size-related return, exchange, conversion and repeat-purchase rates.
- Availability of category-specific standards for womenswear, childrenswear, innerwear, footwear and plus-size apparel.
- Manufacturer and retailer requests for transition periods, inventory exemptions or dual-labelling provisions.
- Build a crosswalk from current size labels and garment measurements to the Indian Size System before new-season production is locked.
- Display standard size, garment measurements, model measurements and fit descriptors together rather than replacing fit guidance with a single label.
- Use return-reason data to identify categories where standard labels will have the largest impact, particularly trousers, denim, bras, formalwear and fitted womenswear.
- Require marketplace sellers to provide structured measurements and standard-size mappings to improve search filters and comparison tools.
- Track whether lower size-led returns are offset by higher exchanges; optimise for net reverse-logistics cost and retained demand, not return rate alone.
- Preserve brand-specific fit options such as slim, regular, relaxed, petite and curvy, using the standard as a baseline rather than a uniform silhouette.
